I don't have a dog in this show, and in fact I don't know any of the folks you are referring to. However, with over 25 years in Law Enforcement, and I think I can say first, it is not mail fraud, and not a Federal case. And even if you could convince someone otherwise, I doubt very seriously if any "G-Men" are going to be assigned to track down the dastardly criminal that stole your 1978 Sound board. It's obvious the guy is having some issues, and it sounds like he wants to do the right thing and is just a bit overwhelmed. I'm sure you will get your board back. My suggestion is to send a registered letter if you now his address, and politely ask him to return it to you. Key word being "politely". In the great scheme of life and death, and with all of the issues going on in the world.....this is hardly something worth getting upset over. It is just a material object that can be replaced...........now pardon me while I slip away from the computer to go hug my kids.
